Major analysis confirms global warming is real

Your science denialist tactic of asking the same questions over and over, ignoring the answers already given, You appear to be confusing me with somebody else. I personally have never asked if the earth was warming in (say) 1961. I still don't know. Hopefully the link you provide will answer my question, when you post it. might work with the peanut gallery on pseudoscience sites like that of Watts, but you're on a science forum here... way out of your depth. I have no idea what you are talking about. I just want a scientific term defined. That term being "global warming". Such that given a complete temperature record, the definition will allow us to determine if global warming is occurring or not at any particular time. This is needed because the referenced paper talked about global temperatures at different times, but you seem to be talking about "global warming". To see if your conclusions follow, we need a way of translating statements about temperature into statements about global warming, which means a definition of global warming. Anyway, even though I only wrote the questions yesterday, according to you the answers are readily available on the internet. Or maybe you could just provide your definition of "global warming"; it is a term that you use and hence I would assume that you know what it means, or at least have some meaning in mind. |

It's an increase in the worldwide mean temperature, due to increased levels of greenhouse gases in the atmosphere. ________________________________________ In that case, the study did *not* confirm global warming is real. It did not consider the causes of warming at all, it only verified that the earth has indeed warmed and cooled at varous times over the last 200 years. By your definition, global warming did not occur at the end of previous ice ages. (Whilst the temperatures increased, this was not preceded by increases in greenhouse gas levels.) And its still a very poor definition. It doesn't actually answer the question. Here is the example I gave befo Take for example http://en.wikipedia.org/wiki/File:In...ord_(NASA).svg The 5 year average global temperature was lower in 1963 than at any time since 1935. Was "global warming" occurring in (say) 1961? How do you know? What calculation based on temperatures (which is what was measured) determines if "global warming" is occurring or not occurring at some point in time? I can't see how your definition answers the question as to whether there was "global warming" at any time between 1935 and 1963. In fact I can't see how it can be used to determine that global warming was occuring at any point in time. Could you provide a worked example which shows us how a global temperature record (such as that confirmed by this study) can be used to determine if global warming is occuring at any point in time? Thanks in advance Peter Webb |

You don't have the intellectual capacity to understand them- as demonstrated many times. I'm not wasting my time on a science denier. So you can't give me a link to the answers. Which rather makes a lie of your statement that you have provided them many times before. Here is a hint, for those unfamiliar with science. If you can't define a term, then you can't make scientific statements regarding that term. Have a look at what regular sciences do. For example, Einstein's theory or relativity states there is no such thing as absolute simultaneity. Einstein first defined this concept (and some others regarding simultaneity) before making any statements concerning its properties. In fact, in all sciences you will find the terms that it uses to be well defined. Chemistry defines terms like pH, mole, triple point, partial pressure, polymer, ion, valence and many others, which is a pre-condition for being able to talk about properties like pH, mole, triple point, partial pressure, polymer, ion, and valence. If climate "science" is to make statements about "global warming" (as indeed the title of this thread does), then it has to define the term. All I want is the definition of this term, such that given a temperature record we can determine whether "global warming" was occurring at that time. For example, was global warming occurring in 1961? It is a very simple question. It just requires you to define "global warming". Why won't you do that? Does it have a definition, or is it a meaningless term? |

You add or change a small detail in your question, then you claim your question is completely new even though it's just a small variation of questions you've already asked many times before.

Or point me to where the question has been answered in the past? I just want a scientific term defined. That term being "global warming". That definition is simple: there is a global warming if the global mean temperature increases. It's no more complex that that. Increases since when? The day before? The year before? The decade before? An increase implies a difference between two numbers. I am guessing that one of the numbers is the average global temperature for that year. I am also guessing that the other is the average global temperature during some different year. Is this correct? What is the "other" year which is used for comparison? Have you got a single calculation which shows that global warming has ever occured? Was global warming happening in 1961?

Lets imagine that you had access to complete and accurate temperature records - say the records which have been published for the last 150 years are perfectly correct. What formula/algorithm/definition allows you to determine when global warming did or not occur within that period of (assumed) perfect and complete temperature records? And here's where your agenda reveals itself: you want to avoid the obvious conclusions, and you do so by requesting unattainable perfection. No. I do not ask for any perfection. I don't actually care about the possible inaccuracies in the temperature record; they are the best we have.

Imagine that the all of the values given in the graph http://en.wikipedia.org/wiki/File:In...ord_(NASA).svg are absolutely correct and perfect. During which years was global warming occurring? How did you work that out? |

Of course you don't know what 'wise' is, that's why you ask those sillyquestions. Have you got a single calculation which shows that global warming has ever occurred? No calculations needed - if there neved had been any global warming, it would still be as cold as during the ice ages. Obviously that's not the case, therefore we've had global warmings.

Woukdnt't it be more interesting to know about the global warming over the entire time period of the diagram? I just picked 1961 as an example, so you could illustrate the rule for determining if global warming is occuring at a particular time. Any or all other years would suffice equally well. There you go again! You add or change a small detail in your question, then you claim your question is completely new even though it's just a small variation of questions you've already asked many times before. And never been answered. You didn't understand the answers...... I never got any. I am just after a definition of "global warming" sufficient to determine whether it is occuring at any particular time (assuming you had full knowledge of the variables that you use, such as a complete record of previous and subsequent global temperatures). Most scientific definitions take about a sentence. For example I can define "Mole", "Valency", "Acceleration", "Prokaryotic", and a bazillion other words by science in a sentence. What is the problem with simply giving a definition of "global warming" in the same manner as real sciences define their terms? I just want a scientific term defined. That term being "global warming". That definition is simple: there is a global warming if the global mean temperature increases. It's no more complex that that. Increases since when? The day before? The year before? The decade before? An increase implies a difference between two numbers. I am guessing that one of the numbers is the average global temperature for that year.

Immediately you pick apart the question with those gory little details. There are no fixed answers to all your little questions -- you have to make wise choices of those parameters. So "global warming" has no fixed meaning? It can mean whatever you want, and you don't have to say what it is? So I could pick the period of the baseline to commence 20 million years ago, in which case we are undergoing global cooling, or I could pick it as 150 years in which case we are undergoing global warming? Are their any other fields of science that you know of where key terms have no fixed meaning? And what is the meaning of "Global Warming" in the statement "Major analysis confirms global warming is real"? If you use a 20 million year baseline for the measurement, then it is certainly false. Its probably false if you use a 10 year baseline. Without a fixed meaning to the term "global warming". I am struggling to interpret what the statement "global warming is real" is actually supposed to mean in terms of the temperature record. Do you know? Can you tell me? Of course you don't know what 'wise' is, that's why you ask those sillyquestions. Have you got a single calculation which shows that global warming has ever occurred? No calculations needed - if there neved had been any global warming, it would still be as cold as during the ice ages. Obviously that's not the case, therefore we've had global warmings. But when? Was their global warming in 1961? Can you identify a single year, in which global warming occured, and tell us how you determined that global warming occured in thet year? Was global warming happening in 1961? If it was, when did it increase from which means that global warming was occuring? If it wasn't when was the period over which there was no temperature difference? ....and how do you intend to use the answers to those silly little questions? By looking at how you determined if global warming occured in 1961, and use this to reverse engineer a definition for global warming. Treat it as a worked example. So, was their global warming in 1961, and how did you determine the answer? I realise that their are limits to measurement. That is not the issue. Lets imagine that you had access to complete and accurate temperature records - say the records which have been published for the last 150 years are perfectly correct. What formula/algorithm/definition allows you to determine when global warming did or not occur within that period of (assumed) perfect and complete temperature records? No single formula is sufficient, you must supplement your formulae with wise judgement. Of course the word 'wise' is completely alien to you, so I expect you to go bonkers when trying to reply to this. It has no fixed meaning? You can change its meaning to suit whatever argument you want? And you don't even have to state which meaning you are using? What definition of "global warming" applies to the subject of this thread, "Major analysis confirms global warming is real"? Or is it undefined, in which case this statement is meaningless? And here's where your agenda reveals itself: you want to avoid the obvious conclusions, and you do so by requesting unattainable perfection. No. I do not ask for any perfection. I don't actually care about the possible inaccuracies in the temperature record; they are the best we have. I simply want a definition of "global warming", such that given an idealised perfect and complete temperature record the periods during which global warming occurred can be identified. You should care about the inaccuracies because they do matter.... Not to a definition of global warming, they don't. There are lots of physical things that are hard to measure in practice, but nevertheless have precise definitions. It is very hard to accurately measure the specific heat or pH of a substance in practice, but they both have very precise definitions - as indeed all scientific terms do (except apparently "global warming", "extreme weather", and some other from climate "science".) Imagine that the all of the values given in the graph http://en.wikipedia.org/wiki/File:In...e_Record_(NASA ).svg are absolutely correct and perfect. During which years was global warming occurring? How did you work that out? The answer to that question isn't particularly interesting. It's the overall picture that's interesting. Why don't you answer the question? I personally am very interested by what the term "global warming" is supposed to mean, because I hear it a lot but have never seen a definition. Now you tell me it has no fixed meaning at all, and there is no way of determining of global warming was occurring at any specific time in history. Which then makes the statement " Major analysis confirms global warming is real" completely meaningless, because "global warming" is undefined. Which, incidentally, is the point I first made when entering this thread. What is it with cranks inventing words to support their theories but never defining them? We have enough problems with relativity cranks talking about the "ether" without defining what they mean, without you AGW believers doing the same with "global warming". |
